ChatGPTとは
Control your browser with ChatGPT. OVERVIEW
The ChatGPT in Chrome extension gives you the full power of ChatGPT directly inside your browser, next to where you work via side chat, and enables the desktop app to control your browser.
ChatGPT understands context across all your tabs, can drive the browser to automate tasks, and has the full capabilities of the Codex app including your installed plugins, existing threads, and the file system.
For any task, ChatGPT will intelligently pick the right tool for the job. If it needs the browser, ChatGPT will work in the background without ever taking over your active browsing session, so you always stay in control.
ChatGPT always asks before sensitive actions like accessing new sites, referencing your browser history, and downloading/uploading files.
